of Positive Philosophy (1830)

CHAPTER 1

Account of the Aim of This Work;
View of the Nature and Importance of the Positive Philosophy

A general statement of any system of philosophy may be either a sketch of a doctrine to
be established, or a summary of a doctrine already established. If greater value belongs
to the last, the first is still important, as characterizing from its origin the subject
to be treated. In a case like the present, where the proposed study is vast and hitherto
indeterminate, it is especially important that the field of research should be marked
out
with all possible accuracy. . . .

In order to understand the true value and character of the positive philosophy, we must
take a brief general view of the progressive course of the human mind, regarded as a
whole, for no conception can be understood otherwise than through its history.

From the study of the development of human intelligence, in all directions, and through
all times, the discovery arises of a great fundamental law, to which it is necessarily
subject, and which has a solid foundation of proof, both in the facts of our organization
and in our historical experience. The law is this: that each of our leading conceptions --
each branch of our knowledge -- passes successively through three different theoretical
conditions: the theological, or fictitious; the metaphysical, or abstract; and the
scientific, or positive. In other words, the human mind, by its nature, employs in its
progress three methods of philosophizing, the character of which is essentially different,
and even radically opposed: namely, the theological method, the metaphysical, and the
positive. Hence arise three philosophies, or general systems of conceptions on the
aggregate of phenomena, each of which excludes the others. The first is the necessary
point of departure of the human understanding, and the third is its fixed and definitive
state. The second is merely a state of transition.

In the theological state, the human mind, seeking the essential nature of beings, the
first and final causes (the origin and purpose) of all effects -- in short, absolute
knowledge -- supposes all phenomena to be produced by the immediate action of supernatural
beings.

In the metaphysical state, which is only a modification of the first, the mind
supposes, instead of supernatural beings, abstract forces, veritable entities (that is,
personified abstractions) inherent in all beings, and capable of producing all phenomena.
What is called the explanation of phenomena is, in this stage, a mere reference of each to
its proper entity.

In the final, the positive, state, the mind has given over the vain search after
absolute notions, the origin and destination of the universe, and the causes of phenomena,
and applies itself to the study of their laws -- that is, their invariable relations of
succession and resemblance. Reasoning and observation, duly combined, are the means of
this knowledge. What is now understood when we speak of an explanation of facts is simply
the establishment of a connection between single phenomena and some general facts, the
number of which continually diminishes with the progress of science.

The theological system arrived at the highest perfection of which it is capable when it
substituted the providential action of a single Being for the varied operations of the
numerous divinities that had been before imagined. In the same way, in the last stage of
the metaphysical system, men substitute one great entity (Nature) as the cause of all
phenomena, instead of the multitude of entities at first supposed. In the same way, again,
the ultimate perfection of the positive system would be (if such perfection could be hoped
for) to represent all phenomena as particular aspects of a single general fact -- such as
gravitation, for instance.

. . . The progress of the individual mind is not only an illustration, but an indirect
evidence of that of the general mind. The point of departure of the individual and of the
race being the same, the phases of the mind of a man correspond to the epochs of the mind
of the race. Now, each of us is aware, if he looks back upon his own history, that he was
a theologian in his childhood, a metaphysician in his youth, and natural philosopher in
his manhood. All men who are up to their age can verify this for themselves.

Besides the observation of facts, we have theoretical reasons in support of this law.

The most important of these reasons arises from the necessity that always exists for
some theory to which to refer our facts, combined with the clear impossibility that, at
the outset of human knowledge, men could have formed theories out of the observation of
facts. All good intellects have repeated, since Bacons time, that there can be no
real knowledge but that which is based on observed facts. This is incontestable, in our
present advanced stage; but, if we look back to the primitive stage of human knowledge, we
shall see that it must have been otherwise then. If it is true that every theory must be
based upon observed facts, it is equally true that facts cannot be observed without the
guidance of some theory. Without such guidance, our facts would be desultory and
fruitless; we could not retain them: for the most part we could not even perceive them.

Thus, between the necessity of observing facts in order to form a theory, and having a
theory in order to observe facts, the human mind would have been entangled in a vicious
circle, but for the natural opening afforded by theological conceptions. This is the
fundamental reason for the theological character of the primitive philosophy. This
necessity is confirmed by the perfect suitability of the theological philosophy to the
earliest researches of the human mind. It is remarkable that the most inaccessible
questions -- those of the nature of beings and the origin and purpose of phenomena --
should be the first to occur in a primitive state, while those that are really within our
reach are regarded as almost unworthy of serious study. The reason is evident enough: that
experience alone can teach us the measure of our powers; and if men had not begun by an
exaggerated estimate of what they can do, they would never have done all that they are
capable of. Our organization requires this. At such a period there could have been no
reception of a positive philosophy, whose function is to discover the laws of phenomena,
and whose leading characteristic it is to regard as interdicted to human reason those
sublime mysteries that theology explains, even to their minutest details, with the most
attractive facility. It is just so under a practical view of the nature of the researches
with which men first occupied themselves. Such inquiries offered the powerful charm of
unlimited empire over the external worlda world destined wholly for our use, and
involved in every way with our existence. The theological philosophy, presenting this
view, administered exactly the stimulus necessary to incite the human mind to the irksome
labor without which it could make no progress. We can now scarcely conceive of such a
state of things, our reason having become sufficiently mature to enter upon laborious
scientific researches without needing any such stimulus as wrought upon the imaginations
of astrologers and alchemists.

. . . The human understanding, slow in its advance, could not step at once from the
theological into the positive philosophy. The two are so radically opposed that an
intermediate system of conceptions has been necessary to render the transition possible.
It is only in doing this that metaphysical conceptions have any utility whatever. In
contemplating phenomena, men substitute for supernatural direction a corresponding entity.
This entity may have been supposed to be derived from the supernatural action; but it is
more easily lost sight of, leaving attention free for the facts themselves, till, at
length, metaphysical agents have ceased to be anything more than the abstract names of
phenomena. It is not easy to say by what other process than this our minds could have
passed from supernatural considerations to natural, from the theological system to the
positive.

The law of human development being thus established, let us consider what is the proper
nature of the positive philosophy.

As we have seen, the first characteristic of the positive philosophy is that it regards
all phenomena as subjected to invariable natural laws. Our business is
-- seeing
how vain is any research into what are called causes, whether first or
final -- to pursue an accurate discovery of these laws, with a view to reducing them to
the smallest possible number. By speculating upon causes, we could solve no difficulty
about origin and purpose. Our real business is to analyze accurately the circumstances of
phenomena, and to connect them by the natural relations of succession and resemblance. The
best illustration of this is in the case of the doctrine of gravitation. We say that the
general phenomena of the universe are explained by it, because it connects under
one head the whole immense variety of astronomical facts; exhibiting the constant tendency
of atoms towards each other in direct proportion to their masses, and in inverse
proportion to the squares of their distances; while the general fact itself is a mere
extension of one that is perfectly familiar to us and that we therefore say that we
know -- the weight of bodies on the surface of the earth. As to what weight and
attraction are, we have nothing to do with that, for it is not a matter of knowledge at
all. Theologians and metaphysicians may Imagine and refine about such questions, but
positive philosophy rejects them. When any attempt has been made to explain them, it has
ended only in saying that attraction is universal weight, and that weight is terrestrial
attraction -- that is, that the two orders of phenomena are identical, which is the point
from which the question set out. Again, M. Fourier, in his fine series of researches on
heat, has given us all the most important and precise laws of the phenomena of heat, and
many large and new truths, without once inquiring into its nature, as his predecessors had
done when they disputed about calorific matter and the action of a universal ether. In
treating his subject in the positive method, he finds inexhaustible material for all his
activity of research, without betaking himself to insoluble questions.

Before ascertaining the stage that the positive philosophy has reached, we must bear in
mind that the different kinds of our knowledge have passed through the three stages of
progress at different rates, and have not therefore arrived at the same time. The rate of
advance depends on the nature of the knowledge in question so distinctly that, as we shall
see hereafter, this consideration constitutes an accessory to the fundamental law of
progress. Any kind of knowledge reaches the positive stage early in proportion to its
generality, simplicity, and independence of other departments. Astronomical science, which
is above all made up of facts that are general, simple, and independent of other sciences,
arrived first; then terrestrial physics; then chemistry; and, at length, physiology.

It is difficult to assign any precise date to this revolution in science. It may be
said, like everything else, to have been always going on, especially since the labors of
Aristotle and the school of Alexandria, and then from the introduction of natural science
into the West of Europe by the Arabs. But, if we must fix upon some marked period, to
serve as a rallying point, it must be that about two centuries ago -- when the human mind
was astir under the precepts of Bacon, the conceptions of Descartes, and the discoveries
of Galileo. Then it was that the spirit of the positive philosophy rose up in opposition
to that of the superstitious and scholastic systems that had hitherto obscured the true
character of all science. Since that date, the progress of the positive philosophy and the
decline of the other two have been so marked that no rational mind now doubts that the
revolution is destined to go on to its completion -- every branch of knowledge being
sooner or later brought within the operation of positive philosophy. This is not yet the
case. Some are still lying outside, and not till they are brought in will the positive
philosophy posses that character of universality that is necessary to its definitive
constitution.

. . . It would be absurd to pretend to offer this new science at once in a complete state.
Others, less new, are in very unequal conditions of forwardness. But the same character of
positivity that is impressed on all the others will be shown to belong to this. This once
done, the philosophical system of the moderns will be in fact complete, as there will then
be no phenomenon that does not naturally enter into some one of the five great categories.
All our fundamental conceptions having become homogeneous, the positive state will be
fully established. It can never again change its character, though it will be forever in
course of development by additions of new knowledge. Having acquired the character of
universality which has hitherto been the only advantage resting with the two preceding
systems, it will supersede them by its natural superiority, and leave to them only a
historical existence.

. . . The purpose of this work is not to give an account of the natural sciences. Besides
that it would be endless, and that it would require a scientific preparation such as no
one man possesses, it would be apart from our object, which is to go through a course of
not positive science but positive philosophy. We have only to consider each fundamental
science in its relation to the whole positive system, and to the spirit which
characterizes it; that is, with regard to its methods and its chief results.

The two aims, though distinct, are inseparable; for, on the one hand, there can be no
positive philosophy without a basis of social science, without which it could not be
all-comprehensive; and, on the other hand, we could not pursue social science without
having been prepared by the study of phenomena less complicated than those of society, and
furnished with a knowledge of laws and anterior facts that have a bearing upon social
science. Though the fundamental sciences are not all equally interesting to ordinary
minds, there is no one of them that can be neglected in an inquiry like the present; and,
in the eye of philosophy, all are of equal value to human welfare. Even those that appear
the least interesting have their own value, either on account of the perfection of their
methods, or as being the necessary basis of all the others.

. . . The general spirit of a course of positive philosophy having been thus set forth, we
must now glance at the chief advantages that may be derived, on behalf of human
progression, from its study. Of these advantages, four may be especially pointed out.

1. The study of the positive philosophy affords the only rational means of exhibiting
the logical laws of the human mind, which have hitherto been sought by unfit methods. To
explain what is meant by this, we may refer to a saying of M. de Blainville, in his work
on comparative anatomy, that every active, and especially every living, being may be
regarded under two relations -- the static and the dynamic; that is, under conditions or
in action. It is clear that all considerations range themselves under the one or the other
of these heads. Let us apply this classification to the intellectual functions.

If we regard these functions under their static aspect -- that is, if we consider the
conditions under which they exist -- we must determine the organic circumstances of the
case, which inquiry involves it with anatomy and physiology. If we look at the dynamic
aspect, we have to study simply the exercise and results of the intellectual powers of the
human race, which is neither more nor less than the general object of the positive
philosophy. In short, looking at all scientific theories as so many great logical facts,
it is only by the thorough observation of these facts that we can arrive at the knowledge
of logical laws. These being the only means of knowledge of intellectual phenomena, the
illusory psychology, which is the last phase of theology, is excluded. It pretends to
accomplish the discovery of the laws of the human mind by contemplating it in itself; that
is, by separating it from causes and effects. Such an attempt, made in defiance of the
physiological study of our intellectual organs, and of the observation of rational methods
of procedure, cannot succeed at this time of day.

The positive philosophy, which has been rising since the time of Bacon, has now secured
such a preponderance that the metaphysicians themselves profess to ground their pretended
science on an observation of facts. They talk of external and internal facts, and say that
their business is with the latter. This is much like saying that vision is explained by
luminous objects painting their images upon the retina. To this the physiologists
reply that another eye would be needed to see the image. In the same manner, the mind may
observe all phenomena but its own. It may be said that a mans intellect may observe
his passions, the seat of the reason being somewhat apart from that of the emotions in the
brain; but there can be nothing like scientific observation of the passions, except from
without, as the stir of the emotions disturbs the observing faculties more or less. It is
yet more our of the question to make an intellectual observation of intellectual
processes. The observing and observed organ are here the same, and its action cannot be
pure and natural. In order to observe, your intellect must pause from activity; yet it is
this very activity that you want to observe. If you cannot effect the pause, you cannot
observe; if you do effect it, there is nothing to observe. The results of such a method
are in proportion to its absurdity. After two thousand years of psychological pursuit, no
one proposition is established to the satisfaction of its followers. They are divided, to
this day, into a multitude of schools, still disputing about the very elements of their
doctrine. This interior observation gives birth to almost as many theories as there are
observers. We ask in vain for any one discovery, great or small, that has been made under
this method. The psychologists have done some good in keeping up the activity of our
understandings, when there was no better work for our faculties to do; and they may have
added something to our stock of knowledge. If they have done so, it is by practicing the
positive method by observing the progress of the human mind in the light of science; that
is, by ceasing, for the moment, to be psychologists.

The view just given in relation to logical science becomes yet more striking when we
consider the logical art.

The positive method can be judged of only in action. It cannot be looked at by itself,
apart from the work on which it is employed. At all events, such a contemplation would be
only a dead study, which could produce nothing in the mind that loses time upon it. We may
talk forever about the method, and state it in terms very wisely, without knowing half so
much about it as the man who has once put it in practice upon a single particular of
actual research, even without any philosophical intention. Thus it is that psychologists,
by dint of reading the precepts of Bacon and the discourses of Descartes, have mistaken
their own dreams for science.

Without saying whether it will ever be possible to establish a priori a true
method of investigation, independent of a philosophical study of the sciences, it is clear
that the thing has never been done yet, and that we are not capable of doing it now. We
cannot as yet explain the great logical procedures, apart from their applications. If we
ever do, it will remain as necessary then as now to form good intellectual habits by
studying the regular application of the scientific methods which we shall have attained.

This, then, is the first great result of the positive philosophy -- the manifestation
by experiment of the laws that rule the intellect in the investigation of truth and, as a
consequence, the knowledge of the general rules suitable for that object.

2. The second effect of the positive philosophy, an effect not less important and far
more urgently wanted, will be to regenerate education.

The best minds are agreed that our European education, still essentially theological,
metaphysical, and literary, must be superseded by a positive training, conformable to our
time and needs. Even the governments of our day have shared, where they have not
originated, the attempts to establish positive instruction; and this is a striking
indication of the prevalent sense of what is wanted. While encouraging such endeavors to
the utmost, we must not, however, conceal from ourselves that everything yet done is
inadequate to the object. The present exclusive specialty of our pursuits, and the
consequent isolation of the sciences, spoil our teaching. If any student desires to form
an idea of natural philosophy as a whole, he is compelled to go through each department as
it is now taught, as if he were to be only an astronomer, or only a chemist; so that, be
his intellect what it may, his training must remain very imperfect. And yet his object
requires that he should obtain general positive conceptions of all the classes of natural
phenomena. It is such an aggregate of conceptions, whether on a great or on a small scale,
which must henceforth be the permanent basis of all human combinations. It will constitute
the mind of future generations. In order for this regeneration of our intellectual system,
it is necessary that the sciences, considered as branches from one trunk, should yield us,
as a whole, their chief methods and their most important results. The specialities of
science can be pursued by those whose vocation lies in that direction. They are
indispensable, and they are not likely to be neglected; but they can never of themselves
renovate our system of education, and, to be of their full use, they must rest upon the
basis of that general instruction that is a direct result of the positive philosophy.

3. The same special study of scientific generalities must also aid the progress of the
respective positive sciences: and this constitutes our third head of advantages.

The divisions that we establish between the sciences are, though not arbitrary,
essentially artificial. The subject of our researches is one: we divide it for our
convenience, in order to deal the more easily with its difficulties But it sometimes
happens -- and especially with the most important doctrines of each science that we need
what we cannot obtain under the present isolation of the sciences -- a combination of
several special points of view; and for want of this, very important problems wait for
their solution much longer than they otherwise need do. To go back into the past for an
example: Descartess grand conception with regard to analytical geometry is a
discovery that has changed the whole aspect of mathematical science and yielded the germ
of all future progress; and it issued from the union of two sciences that had always
before been separately regarded and pursued. The case of pending questions is yet more
impressive; as, for instance, in chemistry, the doctrine of definite proportions. Without
entering upon the discussion of the fundamental principle of this theory, we may say with
assurance that, in order to determine it -- in order to determine whether it is a law of
nature that atoms should necessarily combine in fixed numbers it will be indispensable
that the chemical point of view should be united with the physiological. The failure of
the theory with regard to organic bodies indicates that the cause of this immense
exception must be investigated; and such an inquiry belongs as much to physiology as to
chemistry. Again, it is as yet undecided whether azote is a simple or a compound body. It
was concluded by almost all chemists that azote is a simple body; the illustrious
Berzelius hesitated, on purely chemical considerations; but he was also influenced by the
physiological observation that animals that receive no azote in their food have as much of
it in their tissues as carnivorous animals. From this we see how physiology must unite
with chemistry to inform us whether azote is simple or compound, and to institute a new
series of researches upon the relation between the composition of living bodies and their
mode of alimentation.

Such is the advantage which, in the third place, we shall owe to positive
philosophy -- the elucidation of the respective sciences by their combination. In the
fourth place:

4. The positive philosophy offers the only solid basis for that social reorganization
that must succeed the critical condition in which the most civilized nations are now
living.

It cannot be necessary to prove to anybody who reads this work that ideas govern the
world, or throw it into chaos -- in other words, that all social mechanism rests upon
opinions. The great political and moral crisis that societies are now undergoing is shown
by a rigid analysis to arise out of intellectual anarchy. While stability in fundamental
maxims is the first condition of genuine social order, we are suffering under an utter
disagreement that may be called universal. Till a certain number of general ideas can be
acknowledged as a rallying point of social doctrine, the nations will remain in a
revolutionary state, whatever palliatives may be devised; and their institutions can be
only provisional. But whenever the necessary agreement on first principles can be
obtained, appropriate institutions will issue from them, without shock or resistance; for
the causes of disorder will have been arrested by the mere fact of the agreement. It is in
this direction that those must look who desire a natural and regular, a normal, state of
society.

Now, the existing disorder is abundantly accounted for by the existence, all at once,
of three incompatible philosophies, -- the theological, the metaphysical, and the
positive. Any one of these might alone secure some sort of social order; but while the
three coexist, it is impossible for us to understand one another upon any essential point
whatever. If this is true, we have only to ascertain which of the philosophies must, in
the nature of things, prevail; and, this ascertained, every man, whatever may have been
his former views, cannot but concur in its triumph. The problem once recognized cannot
remain long unsolved; for all considerations whatever point to the a positive philosophy
as the one destined to prevail. It alone has been advancing during a course of centuries,
throughout which the others have been declining. The fact is incontestable. Some may
deplore it, but none can destroy it, nor therefore neglect it but under penalty of
being betrayed by illusory speculations. This general revolution of the human mind is
nearly accomplished. We have only to complete the positive philosophy by bringing social
phenomena within its comprehension, and afterwards consolidating the whole into one body
of homogeneous doctrine. The marked preference that almost all minds, c from the highest
to the commonest, accord to positive knowledge over t vague and mystical conceptions is a
pledge of what the reception of F this philosophy will be when it has acquired the only
quality that it r now wants -- a character of due generality. When it has become complete,
its supremacy will take place spontaneously, and will re-establish order throughout
society. There is, at present, no conflict but between the theological and the
metaphysical philosophies. They are contending for the task of reorganizing society; but
it is a work too mighty for either of them. The positive philosophy has hitherto
intervened only to examine both, and both are abundantly discredited by the process. It is
time now to be doing something more effective, without wasting our forces in needless
controversy. It is time to complete the vast intellectual operation begun by Bacon,
Descartes, and Galileo, by constructing the system of general ideas that must henceforth
prevail among the human race. This is the way to put an end to the revolutionary crisis
that is tormenting the civilized nations of the world.

Leaving these four points of advantage, we must attend to one precautionary reflection.

Because it is proposed to consolidate the whole of our acquired knowledge into one body
of homogeneous doctrine, it must not be supposed that we are going to study this vast
variety as proceeding from a single principle, and as subjected to a single law. There is
something so chimerical in attempts at universal explanation by a single law that it may
be as well to secure this work at once from any imputation of the kind, though its
development will show how undeserved such an imputation would be. Our intellectual
resources are too narrow, and the universe is too complex, to leave any hope that it will
ever be within our power to carry scientific perfection to its last degree of simplicity.
Moreover, it appears as if the value of such an attainment, supposing it possible, were
greatly overrated. The only way, for instance, in which we could achieve the business,
would be by connecting all natural phenomena with the most general law we know
-- which
is that of gravitation, by which astronomical phenomena are already connected with a
portion of terrestrial physics. Laplace has indicated that chemical phenomena may be
regarded as simple atomic effects of the Newtonian attraction, modified by the form and
mutual position of the atoms. But supposing this view provable (which it cannot be while
we are without data about the constitution of bodies), the difficulty of its application
would doubtless be found so great that we must still maintain the existing division
between astronomy and chemistry, with the difference that we now regard as natural that
division that we should then call artificial. Laplace himself presented his idea only as a
philosophic device, incapable of exercising any useful influence over the progress of
chemical science. Moreover, supposing this insuperable difficulty overcome, we should be
no nearer to scientific unity, since we then should still have to connect the whole of
physiological phenomena with the same law, which certainly would not be the least
difficult part of the enterprise. Yet, all things considered, the hypothesis we have
glanced at would be the most favorable to the desired unity.

The consideration of all phenomena as referable to a single origin is by no means
necessary to the systematic formation of science, any more than to the realization of the
great and happy consequences that we anticipate from the positive philosophy. The only
necessary unity is that of method, which is already in great part established. As for the
doctrine, it need not be one; it is enough that it should be homogeneous. It
is, then, under the double aspect of unity of method and homogeneousness of doctrine that
we shall consider the different classes of positive theories in this work. While pursuing
the philosophical aim of all science, the lessening of the number of general laws
requisite for the explanation of natural phenomena, we shall regard as presumptuous every
attempt, in all future time, to reduce them rigorously to one.

Having thus endeavored to determine the spirit and influence of the positive philosophy
and to mark the goal of our labors, we have now to proceed to the exposition of the system
-- that is, to the determination of the universal, or encyclopedic, order, which must
regulate the different classes of natural phenomena, and consequently the corresponding
positive sciences.
